area, ventilation, be studied to clearly show its effect on survival. Controlling ventilation may be the key to improving survival from sudden cardiac arrest.
Sir, I read with interest the editorial “Can survival from outof-hospital cardiac arrest be predicted from a victim’s carbon emissions?”.1 There were some very pertinent comments in the article regarding ventilation that perhaps would be more pertinent if ventilation was always provided in a controlled manner and inadvertent hyperventilation was not rife. This may well cause false readings and subsequent early termination of resuscitative efforts. While the guidelines do comment on controlling ventilation, they do not come out strongly on the need to remove inadvertent hyperventilation from the CPR equation. To date there have been no independent outcome studies on ventilation during CPR. The first landmark study on ventilation during CPR was the study by Tom Aufderheide et al. in 2004. However, this only highlighted the problem of inadvertent hyperventilation and did not show outcomes (except in pigs). With survival rates generally unchanged over the last 15 years (except in pockets around the globe), is it not about time that this one key
